Pan-T Booster Co-expressing MSLN CAR T Cell Therapy in Advanced/Metastatic Solid Tumors

In preclinical study, investigators have demonstrated that the newly developed pan-T booster (harbouring CD40 agonist and one T cell costimulator agonist) co-expressing MSLN CAR T cell possess more powerful antitumor activity than previously reported MSLN-CAR T cells. In this clinical trial, enrolled patients receive an initial dose of pan-T booster co-expressing MSLN CAR T cells at 1×10\^6 cells/kg based on the basic principle of dose escalation design, in order to evaluate the safety, feasibility, pharmacokinetics/pharmacodynamics, and efficacy of pan-T booster co-expressing MSLN CAR T cell in vivo.
